Liam Deane was found dead just a month after being imprisoned for the murder of his daughter.Deane was allegedly killed by prisoner John Westland, who appeared in court following the discovery of Deane’s body.

Deane was charged and jailed after admitting to punching and shaking his 2-day-old daughter Luna because she “would not stop crying.” Luna died three days later as a result of brain injuries. He was sentenced to life in prison for the murder.

“[Deane] said he was responsible for all of the injuries that she had suffered and he said that Luna had not settled down and he lost control,”the prosecutor said in court at the time, Mirror reported.

In my submission there is simply no explanation for the defendant’s [behavior],” Richard Wright, who represented Deane in court in Leeds, England, said at the time.
